Problems solved by technology

[0002] In the existing paddy fields to breed aquatic animals, the ordinary rice used generally has a plant of about 1 meter, and the field water level can only be kept at 10-20 cm when the rice grows. The living space of the aquatic animals is limited, which affects the production of aquatic animals. ; At the same time, if the water level in the field is kept above 40 centimeters, the rice plants are prone to lodging, which will a

Abstract

The invention discloses a method for ecologically cultivating loaches in a paddy. The method includes the following steps that the paddy is fertilized and raked, an outer annular ditch is excavated in the portion, 1-1.5 m away from the edge, in a field ridge, and a cross-shaped ditch or a groined ditch is further excavated in the outer annular ditch to form a communicated cultivating ditch; an escaping prevention device is erected on the outer annular ditch; the outer annular ditch is provided with a water inlet, a drainage opening and an overflow port; the paddy is sterilized by dissolving calcium oxide in water, and the whole paddy is raked next day; fermented manure is applied to the paddy for water fertilizing; seedlings of a rice variety are inserted into the paddy after water fertilizing, wherein the stalks of the seedlings are strong, the seedlings are resistant to lodging, diseases and fertility and grow in deep water, and the yield is high; after the seedlings turn green, loach seedlings are placed into the paddy; feed is thrown during cultivation according to growth conditions of the loaches, and meanwhile the transparent degree of water ranges from 25 cm to 30 cm. The loaches cultivated through the method are natural and free of pollution and are pure green food, little fertilizer is applied to the paddy, fertilizer investment is reduced, and meanwhile the yield of rice harvested from the paddy is increased to some extent.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for ecologically cultivating loach in paddy fields. Background technique [0002] In the existing paddy fields to breed aquatic animals, the ordinary rice used generally has a plant of about 1 meter, and the field water level can only be kept at 10-20 cm when the rice grows. The living space of the aquatic animals is limited, which affects the production of aquatic animals. ; At the same time, if the water level in the field is kept above 40 centimeters, the rice plants are very prone to lodging, which will affect the rice yield. In addition, due to the poor ability of ordinary rice to prevent diseases and insect pests, it is necessary to carry out disease and insect control during the planting process. Pesticides are generally used for disease and insect control, which will affect the growth of aquatic animals, which will not only affect the production of aquatic animals , b...
